I'm working on a series of buildings inspired by the Fallout games. A wealthy businesswoman got panicked by the possibility of nuclear war, bought a huge amount of land, and built residential and community lots-- with most of the useable space underground.

Over time, some of the lots have been made more visually normal, with landscaping, backyard additions, and so on. But I could still use some input on how to make the ground level bunker-style entry section less... bunker-y.

Right now, my focus is fixing this lot: the Underground Start-Up.

My goals:

Keep the entry building looking shed-like, since the idea was that the previous owner was a botanist; and keep the kind of bunker-like vibe, since that's the underlying concept.

Keep the furnished cost at no more than 19,000 simoleons, to make it accessible to brand-new home owners.

Meet MTS's building standards.

My first thoughts: add a bit more decoration-- more plants, for example; or reshape the roof-- maybe give it a curved look, sort of a bunker-hobbit combo; or instead of plain concrete or siding, spring for a stone exterior?

Yes, lots-- I think I can make the cabin one work out reasonably well! Although now I wanna do this one: the little Victorian-ish looking one, too! I think I'd make the upper level all gloomy and dangerous looking... and all the lower levels pastel and sparkly!

(I also think that now I need to do a bus-converted-into-a-house lot, too, but we'll see....)
